The warning is as follow: WARNING: email address 'stable@xxxxxxxxxxxxxxx #5.10' might be better as 'stable@xxxxxxxxxxxxxxx#5.10' So I have no idea what is correct. Is the tool outdated? If so, I will correct my cc and please update the tool. > As commented before, what exactly was corrected ? That is what needs to be > mentioned here.

In fact, in the v2 I was careless to write '!!alt_base'. So I removed the redundant '!' in v3. Please tell me the right cc format, and then I will submit a new v3, without the problems above.
